That's what I don't get, either. You already hold knives when you equip a pistol - and the knife stays out WITH the pistol, so you can shoot an enemy as you run at them and stab when you get close, or vice versa. You don't need knives as a completely separate slot because that would just take away the capability of the pistol....which is stupid.
So, what's the argument here again?
The
discussion is about gameplay options, not which is easiest to use.
Throwing knives and Tomahawks in the CoD series are examples of this. They are not game changing, or even particularly practical, but they add fun to the game, and as a result add gameplay hours. They also require skill to use with any degree of efficiency, as you don't benefit from the slow ADS speed.
The amount of successful melee-using FPS games out are testament to the fact that the separate knife is not necessary, but this does not mean it is not fun or that it would not be liked by the community. Also, the detriment of drawing the knife is minimal if the KZ2 system was used. The knife is drawn with a button (could be done with melee button) and automatically slashes twice as it is drawn. The only thing that would be different is that people can't go around shooting and stabbing, as they'd be responsible for putting their knife away again before they shoot - introducing an element of skill.
At the moment, the votes speak for themselves.
